This paper investigates a new propagation constant measuring technique in which an inductive coupler allows only the selected part of the cable to be measured. The propagation constants are extracted from frequency and time domain measurements. The extracted propagation constants from measurements with an inductive coupler are compared with the reference propagation constant obtained from direc...

In this paper, we propose a preamble structure and appropriate acquisition algorithms for the uplink cable modem. The proposed preamble consists of a serial concatenation of identical constant amplitude zero autocorrelation (CAZAC) sequences. The proposed preamble is used for the frame detection, coarse symbol timing and carrier frequency recovery for the uplink cable modem compliant to data-ov...

Transmission lines are used to transmit energy such as acoustic or electromagnetic waves or bulk of electrical energy from one place to another, and co-axial shielded cable of them. Other means of transportation are two-wires (twisted pair cable and un-twisted pair cable). All such transmission lines are prone to noise coupling from ambient environment, for example, noise from capacitive coupli...

SUMMARY This paper provides a deep insight into fault location on long Submarine Power Cables. Several field results on submarine power cable faults are provided. For land cables the main focus is on the electrical and thermal design of cable insulation and on the electro-thermal and thermo-mechanical design of cable accessories, in order to grant sufficient endurance performances and reliabili...

results the overall prevalence of occupational asthma was 9.7%. this rate was 13.8% in the exposed group. logistic regression analysis showed that even after adjustment for confounding factors, a significant correlation existed between the frequency of occupational asthma and exposure to the produced dust particles (p < 0.05). in addition, age, work experience, body mass index, cigarette smokin...

Operation Support Systems (OSSs) integrate software components and network elements to automate the provisioning and monitoring of telecommunications services. This demonstration illustrates Telcordia’s Cable OSS, and shows how customers may use this OSS to provision IP and telephone services over the cable infrastructure. Telcordia’s Cable OSSs is a process-based application, i.e., a collectio...

BACKGROUND Stainless steel wiring remains the most popular technique for primary sternal closure. Recently, a multifilament cable wiring system (Pioneer Surgical Technology Inc., Marquette, MI, USA) was introduced for sternal closure and has gained wide acceptance due to its superior resistance to tension. We aimed to compare conventional steel wiring to multifilament cable fixation for sternal...

In this paper, the thermal field of underground power cable is solved using two intelligent techniques which are newly introduced for thermal assessment of power cables. A backpropagation neural network (BPNN) and an adaptive neuro-fuzzy inference system (ANFIS) models were developed to predict the cable temperature under geometrical parameter variations. The effect of cable spacing and cable b...
